Since the APC Index Mismatch BSOD is usually caused by a faulty driver, a good way to fix the problem is to check for new updates on your computer. You can check for new drivers through Windows Update. While you’re at it, it’s a good idea to install new system updates to fix bugs and improve your system’s stability.

Apc_index_mismatch in Windows 10 is an error caused by driver incompatibility or faulty hardware. Windows stop code 0x00000001 or apc_index_mismatch is sometimes attributed to Realtek and nvidia drivers. For this reason, in order to fix the problem, you must identify the driver and then uninstall or disable it.

 

Blue Screen errors are the worst, but knowing what to do to resolve the problem will help you get your computer back and your work done. They can happen even after you upgrade your OS to the latest version. An example is the STOP ERROR: APC_INDEX_MISMATCH.
You may have received this error after upgrading to Windows 10. It sometimes comes with any of these error codes: 0x0000001, 0xC6869B62, 0x97503177 or 0x02A7DA8A.

This BSOD error message mainly appears when you have incompatible hardware or driver. To be more specific, display driver and audio driver make such issue on Windows 10. The error message itself should give away the information of the driver or file that caused the failure. According to Microsoft, “The most common cause of this bug check is when a file system or driver has a mismatched sequence of calls to disable and re-enable APCs.”
Here are some of the things you can do if you experience this kind of problem.
Edit startup items, disable audio driver first and then reinstall if corrupted

The audio driver might have been corrupted. If that is so, it will affect other processes and can lead to startup error. To see if this is indeed the culprit, disable it first and then find out if the error will go away. First, run Task Manager and disable the audio device from the Startup tab. It would usually say Realtek HD Audio Manager. Check by restarting your computer. If the error did not occur, then go to Device Manager, right click on audio device and click uninstall device. Restart your computer to have a fresh copy installed automatically by your computer.

Update/reinstall display driver

The other driver that can cause this error is the display driver. First, you may go to Device Manager, update your driver. It usually fixes the problem but if that doesn’t work, uninstall the driver then reinstall a fresh copy. Make sure you have the correct driver for your computer.
